Blog Article

Sinonasal teratocarcinomasarcomas (SNTCS) are really rare, highly malignant and locally aggressive tumors, with a high recurrence and metastasizing rates.The average survival is less than 2 years.Recurrence is very common and usually appears within 3 years.

We present here an interesting case of SNTCS with intracranial extension, completely involving the sinonasal cavity and right orbit, and extending posteriorly to the nasopharyngeal cavity.The patient underwent an extensive surgical procedure which included tumor resection along with right orbital exenteration and midface resection to ensure negative surgical margins.The postablative NEW Bosch PVS651FB1E 60 cm Induction hob - Black Glass dural defect was reconstructed with the free temporalis muscle fascial graft, and post-ablative viscerocranial defect was reconstructed with the free miocutaneus rectus abdominis flap.

Three months after the first operation the patient underwent salvage surgery due to the cytomorphologically confirmed recurrence in the region I on the right side of the neck.Extended radical neck dissection with total parotidectomy was performed, alongside with the resection of the involved skin.Post-ablative Honey defect was reconstructed with the right pectoralis major miocutaneous flap.

Adjuvant treatment in the form of radiotherapy and chemotherapy was administered.The patient is now free from disease at a regular one-year postoperative follow-up.Keywords: Nasal cavity, Paranasal sinuses, Neoplasms, Surgical flaps, Neck dissection, Chemoradiotherapy.
